JOHN OOATES BASHFORD, OF YONKERS, NEW YORK.

VEHICLE-GEAR.

Specification of Letters Patent.

Application filed April 13. 1907- Serial No. 367.968-

Patented Jan. 28, 1908.

To all whom it may concern:

Be it known that I, JOHN CoATEs BASH- FORD, a citizen of the UnitedStates, residing at Yonkers, in the county of Westchester and State ofNew York, have invented certain new and useful Improvements in Vehicle-Gears; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in attachments forvehicle gears and my object is to provide means to compensate for thewear of the pivoted parts of the vehicle.

A further object is to provide means for varying the height of the frontportion of the vehicle with respect to its supporting axle.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings which are made a part of this application,Figure 1 is a detail perspective view of the front portion of therunning gear of a vehicle showing the usual form of pole and swingletrees attached thereto. Fig. 2 is a central vertical sectional viewthrough the front axle of the vehicle and parts carried thereby. Fig. 3is a detail sectional view through the central portion of the pole andshowing the manner of securing the double tree thereto, Fig. 4 is adetail sectional view through the double tree and showing the manner ofsecuring the swingle tree thereto.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views 1 'indicates the frontsupporting axle of a vehicle which is of the usual or any and is adaptedto carry the front end of a reach bar 2, the reach bar in this instancebeing formed of two bars and connected together at their forward end bya head block 3 upon which is mounted the usual form of supporting spring4.

Vehicles as commonly manufactured at the present time employ a king-boltor fifth wheel to secure the two supporting parts of the vehicle to thefront axle but it is my desire to dispense with the fifth wheel andinstead employ suitable supporting means between the axle and partscarried thereby to prevent wear between the parts and at the preferredform same time provide the usual pivotal connection and in this instanceI employ a clip 5 which is disposed over the central portion of the axle1 and is provided with an upwardly extending shaft 6 which is providedon its exterior with threads 7 which are adapted to en gage a threadedbore 8 in a plate 9, said plate being secured to the lower edge of thehead block 3 in any preferred manner as by bolts 10.

An auxiliary plate 1 1 is disposed below the axle 1 and coincident inextent to the clip 5, said auxiliary plate being employed to secure theclip to the axle by directing the threaded stems 12 on the clip 5through openings in the auxiliary plate and securing the same therein bymeans of nuts 13. The auxiliary plate is likewise provided with adepending shaft 14 which is likewise provided on its exterior withthreads 15 which are adapted to enter a threaded socket 16 on the end ofa brace-bar 17, said brace bar being bifurcated and extended rearwardlyfrom the front axle and in engagement with the reach bars 2.

In securing the parts of the vehicle together the depending shaft 14 isinserted into the socket 16 and the clip and auxiliary plate placed inposition on the axle after which the plate 9 is directed on to the shaft6 and the plate then secured to the head block 3 and the properadjustment of the head block may be had by regulating the distance towhich the shafts are directed into their respective sockets.

The threads upon the respective shafts are formed alike so that when theaxle is turned, one of the shafts will enter its respective socket whilethe opposite shaft will leave its respective socket and vice versa whenthe axle is moved. in the opposite direction. The threads upon theshafts form the bearing surface for the parts and enable n e to dispensewith the usual form of fifth wheel or kingbolt.

In Fig. 3 of the drawing, I have shown the manner of securing the doubletree 18 to the pole 19 of the vehicle, and in this instance I dispensewith the clip 5 and provide the shafts 20 and 21 with base plates 22,and 23, respectively which are secured on opposite sides of the doubletree 18 and the shaft 20 is extended upwardly and into a threaded socket24 carried by the usual form of retaining arm 25 which in turn is fixedto the inner end of the pole 19 while the shaft 21 extends into athreaded thimble 26, seated in 'a bore 27 in the pole, said Shafts 20and 21 being threaded similarly to the shafts 6 and 14 and operating inthe same manner.

' In Fig. 4 I have shown the manner of securing the swingle trees 28 tothe ends of the double tree 18 and in this instance I employ the sameconstruction as is usedfor mounting the double tree upon the pole,except that the socket 24 is carried by a clevis 29, the lower end ofwhich is secured in any manner to the lower surface of the .double tree.

may be successfully applied to use in connection'with automobiles,tenders of locomotives or any other device where it is necessary to havepivotal bearings.

What I claim is:

1. The herein described attachment for vehicles comprising a pair ofshafts, threads extending from end to end of said shafts, means tosecure said shafts to parts of the vehicle and threadedsockets for saidshafts, means to secure said sockets to parts of the vehicle, thethreads on said shafts being so arranged that when the part of thevehicle carrying the shafts is rotated one of the shafts will enter itsrespective socket while the opposite shaft will leave its respectivesocket.

2. The herein described attachment for vehicles comprising thecombination with the swinging axle of a vehicle; of a pair of shafts oneof which extends above and the other below the said axle, means tosecure said shafts to the axle, said shafts being similarly threadedthroughout their lengths,

threaded sockets for said shafts, means to.

secure said sockets to parts of the vehicle, the threads upon saidshafts and in said sockets being so arranged that one of the shafts willenter its respective socket and the op osite shaft leave its respectivesocket when t e axle is swung.

3. The herein described attachment for vehicles comprising thecombination with a swinging portion of the vehicle; ofa pair ofoppositely disposed shafts, means to secure the shafts to the swingingportion of the vehicle, said shafts being similarly threaded and asocket for each of said shafts having threads therein to engage thethreads on the shafts whereby when the parts .of the vehicle are swungthey will be raised or lowered.

4. The herein described attachment for vehicles comprising thecombination with a swinging axle; of a clip adapted to extend over saidaxle, an auxiliary late below said axle, means to secure the ip to saidauxiliary late, an upwardly extending shaft on said 0 ip, a dependingshaft on said plate, said shafts being similarly threaded throughouttheir length, a plate having a bore there in adapted to receive theupwardly extending shaft, a socket for the depending shaft and means tosecure said plate and socket to the parts of the vehicle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
